The Duality of Higher Self and Lower Self

In Zen, a duality between higher self and lower self is not made. If you think you have a lower self or an ego to get rid of, and then you fight against it, nothing strengthens the delusion that it exists more than that. So, this tremendous schizophrenia in human beings of thinking that they are rider and horse simply aggravates the problem. And so, we have all sorts of people engaged in an interior conflict which they will never, never resolve.
